It's really difficult to say. Plants that are sold for the garden are slightly less likely to have been sprayed with insecticide than houseplants, but you just don't know. Washing the leaves would help, and of course if it is a plant that tortoises are unlikely to eat then that's even better, but many tortoises will take a bite of something just to test it.
There are a number of aphids that do affect Bromeliads, but I don't think they are a plant that is especially at risk from aphids. It's difficult to know if the growers have sprayed plants with insecticides, and the shop you buy them from is almost certain not to know, as their plants will have been grown somewhere else and bought in. Luckily Bromeliad leaves are not too difficult to wash as they are tough, so you could try that, but there are no guarantees. What are the plants that you've bought that you intend to plant into the enclosure (some will be less likely to have been sprayed and others could be fast growing so that in a week or two you could pinch off most of the old leaves, and expose the new growth)?
